Overview
The YUE FENG 722 (N) visible spectrophotometer is a precision opticalin strument with a new microcontroller system. It has the characteristics of powerful function, small size and easy maintenance. It uses a flame retardant insulated all-plastic shell, which is beautifully designed, easy to operate and has a high safety factor.
Features
1. Adopt a new type of single-chip microcomputer system, with strong functions, small size, and easy maintenance.
2. The use of flame retardant, insulated plastic shell, exquisite design, easy to operate, high safety factor.
3. True 4-bit LCD display, Measurement range, high calculation accuracy.
4. Membrane keyboard, good feel, dustproof, waterproof and easy to clean.
5. Professional Optical inspection system design, sealing grating monochromator, adopt scientific anti-mildew technology, eliminate stray light technology, significantly improve the service life, stray light, Stability, metering accuracy indicators.
6. Use a lens to concentrate light to avoid a straight drop in energy after the reflector has been ablated for a long time.
7. Special precision lamp holder, can replace the halogen tungsten lamp without having to adjust the light path again.
8. Automatic adjustment 0%, automatic adjustment 100% and Absorption OA.
Principle
The visible spectrophotometer is based on a single beam of light Optical inspection system, using 1200/mm Holographic grating, separating specific wavelength rays of light through a sealing grating monochromator, using lens condensing technology to enhance light energy, automatically adjust transmittance and Absorption, to achieve accurate photometric measurement.
Applications
Chemical analysis, biological testing, environment monitoring, pharmaceutical research and development, food inspection
Steps
1. Turn on the preheating instrument.
2. Measurement parameters set using membrane keyboard.
3. Automatically adjust 0% and 100% to calibrate.
4. Place the sample for transmittance, Absorbance or concentration measurement.
5. Connect external devices (such as the optional Bright thermal printer) to output data through the RS232 interface.
Notice
• The instrument uses a flame retardant insulating shell to ensure safe operation.
• Regularly clean the membrane keyboard to prevent dust and water.
• Use a special precision lamp holder when replacing tungsten halogen lamps, no need to adjust the optical path.
• Avoid prolonged exposure to bright light to extend the life of Optical inspection components.
• Ensure instrument stability before calibrating for accurate measurement results.
